Have driven the truck about 500 miles total the last 2 1/2 years, sits in a temp controlled garage with battery charger but with 1/2 tank of 6 month old gas. Just moved to California so have not driven it in 4 months. Had entire ignition system and exhaust system replaced 2 years ago in NJ (including oxygen sensors and catalytic converter) as it was stalling and this seemed to have fixed things. Now that I moved the truck to California and need it smog checked so want the best chance of passing as a failed test is reported immediately and makes things more complicated. Never had a issue while in NJ passing but recently, no need as it grandfathered out of NJ requirements.
Truck has about 100 K miles. In adding BG 44K, should I drive off the remaining 1/2 tank of old gas first and then add the BG 44K with a full tank of premium gas or just dump the BG 44K in the remaining 1/2 tank of old gas?
